MULTIPLE CHOICE
1. Power is a measure of which of the following?
a. Mechanical energy
b. Gravitational potential energy
c. The rate at which work is being performed
d. The rate at which atoms and molecules move
ANS: C
Power is a measure of the rate at which work is being performed. The formula P = W/J, where
W = watts and 1 watt is equal to 1 J/s, expresses this. Joules are the international standard for
expressing energy and work.
PTS: 1 REF: Page 8
2. When effort produces a change in the position of matter:
a. work is performed.
b. it is known as a joule.
c. mechanical power is created.
d. the law of the conservation of energy is being used.
ANS: A
Work is performed only when effort or outside forces produce a change in the position of
matter.
PTS: 1 REF: Page 8
3. The unit used to express the force of 1 newton (N) acting on a 1-kilogram (kg) object to move
it 1 meter (m) is which of the following?
a. Watt c. Kilowatt
b. Joule d. Kinetic energy
ANS: B
One joule is equal to the force of 1 N acting on 1 kg. A watt is equivalent to 1 J/s. A kilowatt is
simply 1000 W. Kinetic energy is energy an object possesses when it is in motion.
PTS: 1 REF: Page 8
4. Power is expressed in which of the following units?
a. Newtons c. Ohms
b. Joules d. Watts
ANS: D
Power is a measure of the rate at which work is being performed. Energy and work are
measured in joules. One joule is the force of 1 N acting on a 1-kg object to move it 1 m. Ohms
is the resistance an electrical circuit possesses.
